Something to ponder:
No matter how good the cable is that you use, you are never hearing anything "better" than the performance of the cables used in the recording.
And virtually none of the cables, especially for many of the most heralded audiophile classics, were "boutique" cables of the sort we see now. No cryogenic freezing, no cable risers, no specialized proprietary extruding techniques, no 99.99 percent oxygen free copper, no science-fiction-levels low electrical reactance...and all the other marketing. You are hearing the quality of the most basic cable the musical signals ever passed through on the way to being recorded (and mixed, and mastered, etc).
So think about it: every time you hear an advance in quality when you upgrade your cables, all the way up to the very best available in the world right now, every new revelation - those finger tips on the strings, that guy coughing in the 18th row, that incredible nuance in the natural reverb of the hall - all of that is a revelation about what those old non-boutique, non-audiophile, normally-priced cables used in recordings were able to pass along. The most basic ones in the whole chain.
And then ask yourself if boutique audiophile cables are necessary for passing along extremely high fidelity signals.
